Hi! Thank you!
Here's a small list of some places, and people, that are contributing valuable insights or work to the discussion. I mean, there is a lot, but these are a good place to start.
http://www.critical-distance.com/ does great roundups of the best of insights about games, and more nuanced discussion.
Liz Ryerson's writing is really good http://ellaguro.blogspot.com/
her twitter is great to follow: https://twitter.com/ellaguro?lang=en
also her "Beyond The Filter" podcast is super insightful (totally recommend this):
Lana Polansky's writing is good too: https://lanathegun.wordpress.com/published-writing/
also: http://sufficientlyhuman.com/
Leigh Alexander's older commentary on games is still super relevant and amazing. She's very following on twitter too: https://twitter.com/leighalexander
Some other awesome people to follow (there are many, but this is off the top of my head)...
